The ordered pairs below represent the function t(x). What is the value of t(1)
Answers
Answer:
t(1) = -3
Step-by-step explanation:
Functions
We have the function t(x) and some ordered pairs that represent the function:
{(-2,3),(-1,8),(0,-5),(1,-3),(2,-8)}
The ordered pairs have the form ( x , t(x) ). Taking a look at the list of ordered pairs, we find the pair (1,-3), which means
t(1) = -3

3(3x-8)-5(3x-8)=(4x-16)-6(x-2)
Answers
Answer:
the answer should be 5
Step-by-step explanation:
Remove parentheses.
3(3x-8)-5(3x-8)=4x-16-6(x-2)3(3x−8)−5(3x−8)=4x−16−6(x−2)
2 Simplify 3(3x-8)-5(3x-8)3(3x−8)−5(3x−8) to -2(3x-8)−2(3x−8).
-2(3x-8)=4x-16-6(x-2)−2(3x−8)=4x−16−6(x−2)
3 Expand.
-6x+16=4x-16-6x+12−6x+16=4x−16−6x+12
4 Simplify 4x-16-6x+124x−16−6x+12 to -2x-4−2x−4.
-6x+16=-2x-4−6x+16=−2x−4
5 Add 6x6x to both sides.
16=-2x-4+6x16=−2x−4+6x
6 Simplify -2x-4+6x−2x−4+6x to 4x-44x−4.
16=4x-416=4x−4
7 Add 44 to both sides.
16+4=4x16+4=4x
8 Simplify 16+416+4 to 2020.
20=4x20=4x
9 Divide both sides by 44.

A magazine provided results from a poll of 20002000 adults who were asked to identify their favorite pie. Among the 20002000 respondents, 1414% chose chocolate pie, and the margin of error was given as plus or minus±33 percentage points. What values do ModifyingAbove p with caretp, ModifyingAbove q with caretq, n, E, and p represent? If the confidence level is 9999%, what is the value of alphaα?
Answers
Answer:
Step-by-step explanation:
Given that:
The sample size n = 2000
The sample proportion [tex]\hat p[/tex] = 0.14
If [tex]\hat p[/tex] = 0.14, then [tex]\hat q[/tex] = 1 - [tex]\hat p[/tex]
[tex]\hat q[/tex] = 1 - 0.14
[tex]\hat q[/tex] = 0.86
The margin of error = 0.03
Given that the confidence interval level = 99%
The significance level is the value of alpha ∝ = 1 - 0.99
∝ = 0.01
For a special movie premiere, the theater owner decided to charge $20 per ticket for the first r rows of the theater and $15 for the remaining rows. 2. Explain how you could find the owner's total income if you knew the value of r and you knew that all tickets were sold. 3. Suppose r=16. A. Find the income in the first r rows if all of the tickets were sold. B. Find the income in the remaining r rows if all of the tickets were sold. C. Find the total income for r=16. 4. Write and simplify an expression for the owner's profit if tickets are priced at $20 per ticket in the first r rows and $15 per ticket in the remaining rows, if all seats are sold. 5. Evaluate the expression you wrote in Question 4 for r=16 and show that the result equals your answer in Question 3c.
Answers
Answer & Step-by-step explanation:
2. Total income = Income from first r rows + Income from other last rows
[(Price per first r rows' seat ) x (no of first r rows) x (no of seats per first r row) ] + [ (Price per other last rows' seat ) x (no of last rows) x (no of seats per last row) ]
= [ 20 x (r) x (no of seats per first r row) ] + [ 15 x (other last ie 'total - r' rows) x no of seats per last row
3. 20 x 16 x (no of seats per first r row) = 320 x (no of seats per first r row)
4. 15 x (other last ie 'total - 16' rows) x no of seats per last row
Renting a tent from the party supply store costs $100 for the insurance fee and $50 for each hour rented. Write an algebraic expression to represent this situation based on the number of hours the tent was rented. What is the coefficient in the expression
Answers
Answer:
100 + 50h
Step-by-step explanation:
Given
Represent the hour with h.
Insurance Fee = $100
Hours = h
Cost per hour = 50
Required
Determine an algebraic expression
The expression is as follows:
Expression = Insurance Fee + Cost per hour * number of hours
Expression = 100 + 50 * h
Expression = 100 + 50h
The coefficient in the question is the number of hours (h)

The answer for number 3 is y=2x+b.
For number 4, plug in the point values for x and y and solve for b. The point given is (-4,-5).
-5=2(-4)+b Now simplify
-5=-8+b then add 8 to both sides to isolate b
3=b or b=3
For number 9, you now know that m is 2 and b is 3

point M with coordinates (3,4) is the midpoint of the line AB and A has the point (-1,6). what is the point of B?
Answers
Answer:
B = (7, 2)
Step-by-step explanation:
B = 2M -A
B = 2(3, 4) -(-1, 6) = (2·3-(-1), 2·4-6)
B = (7, 2)
_____
The expression for the other end point, B, comes from the equation for the midpoint.
M = (A +B)/2
2M = A + B . . . . . multiply by 2
2M -A = B . . . . . . subtract A to get an expression for B

Cindy, who is self-employed, maintains an office in her home that comprises 16% (260 square feet) of total floor space. Gross income for her business is $44,150, and her residence expenses are as follows: Real property taxes $4,188 Interest on mortgage 6,980 Operating expenses 3,490 Depreciation (based on 16% business use) 3,755 If required, round your final answer to the nearest dollar. a. What is Cindy's office in the home deduction based on the regular method? $ b. What is Cindy's office in the home deduction based on the simplified method? $
Deduction :
Real property taxes = 16% * $4,188 = $670.08
Interest on mortgage = 16% * 6,980 = $1116.80
Operating expenses = 16% * 3,490 = $558.40
Depreciation (based on 16% business use) = 3,755
Total deduction:
$(670. 08 + 1116.80 + 5558.40 + 3755) = $11,100.28
Simplified deduction :
$5 per square foot of home used for business
Number of square feet = 260
$5 * 260 = $1300
